WILMINGTON, DELAWARE, A CORPORATION OF DELAWARE RAZOR Application filed September 17, 1931. Serial No. 563,273.

My invention relates to the safety razor art and more particularly to safety razors employing a double edge flexible elastic blade. v

7 In razors of this type, the flexible blade is clamped in flexed position between a guard member and a cap member. In this position the twobutting edges of-the blade are exposed between the cap and the guard. The degree ofexposure of the cutting edge determines the closeness of the shave obtainable with the razor. The greater the exposure of the edge,

the closer will be the shave. It is desirable for a user to be able to vary the closeness of the shave obtainable, and different users desire shaves of dilferent degrees of closeness. One of the objects of my invention is to provide a razor with which'it is possible to obtain a variety of difierent blade exposures while at the same time maintaining the blade tightly clamped between the guard and the.

cap.

Another object of my invention is to pro-v vide a razor having a cap permanently secured to' the handle and a guard either permanently secured or secured in such manner that it will not be likely to be dropped when the razor is disassembled. 'Such a razor is much more convenient to handle than the separate pieces. Furthermore, the difficulty resulting from bent cap corners is obviated, as there is practically no possibility that the 7 user will accidentally drop the cap and thus vention will appear from the following description considered in connection with the accompanying drawings, which form a part of th's specification and on which:

Referring more particularly to Fig. 1, reference character 10 designates a guard member. Guard 10 is preferably formed out of a single piece of metal. It comprises a central portion 11. Oblong openings 12 may be formed in portion 11 in order to reduce the weight of the guard. Extending laterally from portion 11 are two series of teeth 13 and 14. The teeth 14 are longer than teeth 13.

The outer ends of teeth 13 and 14 may be said to define guarding edges. These guarding edges are at different distances from the longitudinal center line of the guard.

Integral with portion 11 of guard 10 are two pairs of ridges 15 and 16 which extend from each side as shown, respectively, of the guard. Ridges 15 are of less height than ridges 16. Integral-with portion 11 are also four pairs of members 17, two pairs projecting from each side of the guard.

Associated with guard 10 is a curved can member 18 provided with a centrally located threaded pin 19 (see Fig. 7). Pin 19 extends through an opening 20 formed in the central portionot guard 10 and engages a threaded opening formed at the end of a handle 21. A flexible steel blade 22 is placed between guard 10 and cap 18. Blade 22 is. clamped between the cap and one of the pairs of ridges 15 ,or

messes 16 by screwing handle 21 onto pin 19. The tops of ridges 15 and 16 have substantially the same curvature as the concave side of the cap. Blade 22 is provided with two parallel cutting edges 23 and 24. These edges extend beyond cap 18 and may be said to be exposed between the cap and the guarding edge defined by teeth 13 and 14, respectively. Cap 18 is provided with a central ridge 25 which extendsthrough a longitudinal slot in the blade and is engaged between members 17 on guard 10 and retains the cap in its proper position of the blade either for protection purposes or alignment purposes or both.

Four different degrees of-blade exposure.

are obtainable with this razor as is illustrated in Figs. 2 and 3. In these figures dot and dash lines have been drawn tangent to the ends of the teeth on the guard and to the adjacent edge portion of the cap., In Fig. 3 the blade is shown as being clamped between the cap and the lower ridges 15 oil" the guard. Due to the unequal length of teeth 13 and 14, cuttng edges 23 and 24 of the blade are exposed different amounts. Cutting edge 24, which is adjacent the longer teeth 14, is exposed the lesser amount, while cutting edge 23, which is adjacent shorter teeth 13, is exposed the greater amount. This is illustrated by the distance which the cutting edges of the blade extend beyond the tangent lines. .It is apparent that instead of mak ng teeth 13 and 14 of diiierent lengths, they might be the same length if the base of teeth 14 was further from the adjacent ridges 15 and 16 than the base of teeth 13 from the adjacent ridges. The important factor, is the distance to the guarding edge defined by the ends of the adjacent teeth.

In Fig. 2 the guard 10 is shown reversed with respect to cap 18. In this position the blade 22 is clamped between. the cap and ridges 16 of the guard. Inasmuch as ridges 16 are h gher than ridges 15, the cutting edges of the blade have a greater exposure in this pos tion than in the position shown in Fig. 3.

In Fig. 2 cutting edge 23, which is adjacent i guard relative to the cap, there are provided tWo-difi'erent blade exposures, .while by reposition shown in Fig. 2 has the greatest amount of blade exposure obtainable.

In Fig. 4 there is shown the above described modification of my inventionincorporated in a silghtly modified form of razor.

Guard 10 is provided with four pins 26 which extend through the central portion 11 of the guard. These pns replace members 17 shown in Figs.,'1. through 3. The. razor shown in Figs. 4 and 5is'0therwise the same as that shown in Figs. 1 through 3. v

In Figs. 6-through 8 there is shown a modified form of my invention embodying a razor similar to that shown in Figs. 4 and 5. Guard 10 is provided with pins 26 for engaging the ridge of the cap 18 Integral with guard 10 and forming a part thereof are pairs of ridges 27 and 28. Ridges 27 and 28 are ofthe sameheight. Guard 10 is provided with two series of teeth 29 and 30. The'distance from the ridges adjacent to teeth 30 tothe guarding edge defined by the ends of these teeth is greater than the distance from the ridges adjacent the teeth 29 to the guarding edge defined by the ends of teeth 29. Also, the guarding edges are at different distances from the longitudinal center line. The ends of teeth 29 and 30 are rounded or-bevelled. However, the curvature or bevel of the teeth is not the same on both sides thereof. It will be noted thatteeth 29 and 30 have a greater bevel at 31 than they have at 32.

In'Fig. 8 the blade 22 is shown as clamped betweencap 18 and ridges 27 which are on the same sides of the guard as the lesser bevel 32. Edge 24 of the blade is exposed between cap 18 and the side of longer teeth 30 which has the lesser bevel 32. Edge 24 in this position has .the least exposure obtainable with this modification. Edge 23 in Fig. 8 is exposed between the cap and the side of shorter teeth 29 having the lesser bevel 32. Cutting edge 23 has next to the least amount of exposure obta nable. Fig. 7 blade 22 is clamped between the cap and ridges 28 which are on the same side of the guard as is greater bevel 31. Cutting edge 24, which is exposed between the cap and the side of longer teeth 30 having the greater bevel 31 is exposed next to the great est amount obtainable. Edge 23, which is exposed between the ,capand the side of shorter teeth 29 having the greater bevel 31 has the greatest amount of exposure obtainable.

The razor shown in Figs. 9 and 10 embodies Cutting edge 23 in the- In the position shown in the form of invention described in connection with Figs. 1 through 5, that is, the combination of ridges of different heights with guarding edges located different distances from the ridges and the longitudinal center line. 7 Instead of guard 10 being provided with series of teeth defining a guarding edge, there is made integral with the guard bars 35 and 36 connected thereto by end members 37;, There is thus left an oblong opening 38 between the central portion 11 of the guard and the bars 35 and 36. The outer edges of bars 35 and 36 define the guarding edges 'which were defined by the ends of the teeth in the razors previously described. The openings 38 serve the same purpose as the space between the teeth, which is to allow the passage therethrough of lather and prevent the lather from accumulating underneath the blade.

In; the razor shown in Figs. 9 and 10, a cap 39 is provided .with a pair of pins 40 which extend through openings 41 formed in the central portion 11 of guard 10. Pins 40 and openings 41 locate the cap with respect to the guard, as did rid ge25 and members 17, shown in the previous embodiments.

Gu-ard 10 is provided with a pair of ridges 15 extending from one side thereof and a par of higher ridges 16 extending from the other side thereof. Bar 36 is located at a greater distance from adjacent ridges 15 and 16 and from the longitudinal center line than is bar 35 from its adjacent ridges and the longitudinal center line; Thus, four degrees of bladeexposure are obtainable in the same manner as described in connection with Figs. 1 through 3. In Figs. 11 l2 and 13 there is shown the form of my invention previously shown in Figs. 1 through 5 and 9 and 10 but embodied in a somewhat modified form of razor. Guard 10 is provided with a series of teeth 13 and a series of teeth 14. Teeth 14 are longer than teeth 13, the inner end being equidistant from the longitudinal center line. The guard is also provided with a pair of ridges 15 projecting from one side thereof and a pair of ridges 16 extending from the other side. Ridges 16' are higher than ridges 15. The central portion 11 of guard 10 is provided with a pair of slots 42 on either side of a central opening 43. A pin 19 secured to a cap 44 extends through opening 43 and engages the threaded opening in handle 21. Cap 44 is provided with a pair of lugs 45 which extend through openin 42 formed in the guard. Lugs 45 and openings 42 serve t6 properly locate cap 44 with respect to guard 10..- Four degrees of blade exposure may be obtained by reversing the guard with respect to the cap' in the same manner as described in connection with Figs. 1 through 5 and Figs. 9 and 10.

Another modified form of my invention is illustrated in Figs. 14 and 15. The razor shown in these figures comprises a curved cap 22 provided with a central ridge- 25. Both sides of the central portion 11 of guard 10 have a curvature which is substantially the same as the concave curvature of cap 22. Integral with guard 10 are two series of teeth 4:6 and 47. Teeth 47 are longer than teeth 16 and their inner ends are equidistant from the longitudinal center line. The curvature 48 on one side of teeth 46 is different from the curvature 4-9 on the opposite side of the same teeth. The curvature 50 of one side of teeth 4:7 is different from the curvature 51 on the other side of these teeth. Thus, when blade 22 is clamped between cap 18 and guard 10 the exposure of cutting edges 28 and 24of the blade will be diiierent, due to the difference in curvature of the teeth. In the position shown in Fig. 15, cutting edge 24' has the least amount of exposure obtainable.

This edge is exposed between the cap and the side of longer teeth 47 which has the curvature 51. Cutting edge 23 has next to the least amount of exposure obtainable as it is located between the cap and the side of shorter blade l6 having the curvature 49. Cutting edge 24 of blade 22, in the position shown in Fig. 14, has next to the greatest amount of ex posure obtainable as it is exposed between the cap and the side of longer teeth 37 having the curvature 50. Cutting edge 23 has the greatest amount of exposure obtainable as it is exposed between the cap and the side of shorter teeth 46 having the curvature 48. There is thus obtainable with this modification of my invention four different degrees of blade exposure. As in the modification previously described, two different degrees of exposure are obtained when the guard is in one position with respect to the cap and two additional degrees of blade exposure are obtained when the guard is reversed with respect to the cap. i

In the above described forms of the invention, the razors have all had mating parts between the cap and the guard. It will be thread 6 apparent that the invention is equally applicable to a razor in which there is independent mating of the guard and cap respectively with the blade.

In Fig. 16 there is shown a one-piece razor embodying various novel features. The razor comprises a handle 60 having a screw 1 formed near one end thereof. Between screw thread 61 and the end of handle 60 there is formed a circumferential groove 62. Groove 62 is preferably formed by a member 63 having a flange 64 and firmly secured to the end of the handle proper. Guard member 65 has a flange 62a rotatably engaging in groove 62. Guard 65 is provided with two series of teeth 13 and 14, having their inner ends equidistant from the longitudinal center line, but teeth 14 being longer than teeth 13, as was the case in the embodiments previously described.

A pair of members 66, preferably integral with theguard, extend from one end of the guard and are provided with elongated slots 67. Members 66 form one part of a hinge, the other part of the hinge comprising a member 68 extending from a cap 69. A pin extends through the elongated slots 67 and through a cylindrical hole in member 68. The central part of cap 69 is provided with a threaded pin 71, which is adapted to engage threads formed on the inside of member 63 forming part of the handle.

A bar or base member 72 engages the thread 61 formed on handle 60. One end of bar 72 bears against the lower end of member 68 and determines the vertical position of themember. Bar 72 is provided with extension 73, which passes through the opening 74 formed in guard 65 and serves to maintain the bar in alignment with the guard. Opening 74 is made longer than is necessary to accommodate projection 73 although of the same width, in order to balance the weight of the hinge on the adjacent end of the cap and guard.

l/Vhen handle 60 is rotated in a direction such that pin 71 is unscrewed from member 63, bar 72 advances upwardly, as viewed in Fig. 16, on threads 61. The pitch of thread 61 is the same as the pitch of the thread in member 63, and hence pin 71 and bar 72 move at the same rate. When pin 71 is disengaged from member 63, cap 69 may be hinged or swung about pin 70 and the blade 22 may then be removed. When it is desired to reassemble the razor, the cap is swung into position parallel with the guard 65. That the cap will be parallel is assured by bar 72 raising member 68 through a proper distance. When the handle is rotated so as to engage pin 71, the cap is drawn down against the guard, pin 70 sliding in slots 67. There is thus provided a one-piece razor having two degrees of blade exposure due to the different lengths of-teeth 13 and 14.

In Figs. 17 through 21 there is shown a razor having a cap permanently secured to the handle. In fliis embodiment the guard is removable and four degrees of blade exposure may be obtained.

Reference character 75 designates a hollow one end of spindle 76 and enables the user to rotate the spindle. The parts 75, 76 and 78 together form the handle as a whole. Secured to the upper end of handle member 75, as viewed in Fig. 18, is a bar or base member 79. Hinged to one end of bar 79, as is shown at 80, is a cap 69. Cap 69 is provided with a centrally located threaded pin 71. The upper end of spindle 76 has internal screw threads formed therein which are adapted to engage the threads formed-on pin 71.

Bar 79 is provided with a pair of extensions 81, which serve to position a guard member 82. Guard member 82, 'as will "be seen particularly from Fig. 19, is generally similar to the guard member previously described and illustrated in Figs. 1 through 3.

The guard is provided with a series of teeth bar 79 in order to receive the central ridges.

17 of the guard. These ridges 17 bear against the central part of the blade in the region of grooves 17a formed in the cap, as described in connection with previous embodiments.

I The upper end of spindle 76 bears against the central portion of guard 82 and serves to raise the guard and force it against the cap,

thereby clamping the blade between the guard and the cap, when the spindle is rotated. Rotation of the spindle also icauses it to advance upwardly on threaded pin 71. Thus, when the guard is forced against the cap, the cap is held securely by its threaded engagement with the spindle. WVhen the spindle is rotated in the other direction, so as to disengage pin 71 and to lower guard 82, the cap may be hinged away from the guard and the blade removed. In this, as in all other embodiments, all the threads are of the same pitch.

i As will be seen from Fig. 21, the slots in the end of bar 79 adjacent the hinge are made larger than the slots in the other end of the bar in order to compensate for the weight of the hinge and balance the razor.

A still further embodiment of my invention is shown in Figs. 22 through 2th This embodiment is similar to the embodiment last described except that projections 81 on bar or base member 79 extend through slots 87 formed in the central part of cap 69, and that a different type of handle is employed. The handle in this embodiment consists of a single hollow member 88 having external threads 89 formed thereon and internal threads 90 formed within the bore. Threads 89 engage similar threads formed in bar 79 while threads 90 engage threads formed on pin 71 which is secured to the cap. Projections 81 in this modification serve to position the cap as well as the guard. Guard 82 is similar to the guard shown in the previous embodiment except that the projections at.

the corners are omitted. In this embodiment,

Guard cap 69 is provided with projections 55, similar to the projections shown in the cap in Figs. 1 throu h 3.

Rotation oi handle 88 causes the move with respect to bar 79, and if rotated in the proper direction causes it to force guard 82 up against cap 69 while at the same time the handle engages pin 71 of thecap. WVhen the handle is rotated in the opposite direction, it allows guard 82 to drop away from the cap andfinally disengages pin 71. Thereupon the cap may be pivoted away from the guard and the blade removed and the guard turned over in order to obtain a different degree of closeness of shave, if de sired. A flange 91 on the end of handle 88 prevents the handle from being unscrewed from bar 79.

In Figs. 25 and 26 there is shown another embodiment of a one-piece razor. Handle 92 is rotatably journalled in a guard 93. The internal bore of handle 92 is provided with a thread 94: adapted to engage a thread formed on 'pin 71 of cap 69. Cap 69 is hinged at 95 to a spring 96, the other end of spring 96 being secured to guard 93 in any suitable manner, as b rivet 97. Guard 93 is provided with teet 13 and 14, teeth 14 being longer than teeth 13, as in previous embodiments.

When the handle 92 is rotated so as to disengage pin 71, it causes the cap to be raised with respeetito the guard. The cap is provided with projecting lugs 98 whic extend through apertures 99 formed in the guard.

Although cap 69 is permanently secured to guard 93, it is capable of limited movement with respect thereto when the handle is rotated so as to disengage pin 17 due to the resiliency of spring 96.

Another form of one-piece razor is illustrated' in Figs. 27 through 29. In this embodiment handle 100 is provided with an external thread 101 and an internal thread 102. A bar or base member 103 has a thread engaging threads 101 while threads formed on pin 71 of a cap 104; engage threads 102. Cap 104 is rigidly secured to bar 103 by means of pins 105 and 106. Pin 105 extends through a cylindrical hole 107 formed in a guard 108. The other end of guard 108 is formed with a lip 109 having a semi-circular recess handle to" 110, which is adapted to engage pin 106.

08 may therefore be rotated in a clockwise direction, as viewed in Fig. 29, about pin 105 when handle 100 is in its lowermost position, as seen in Fig. 27. Rotation of handle 100 in one direction serves to force guard 108 against cap 104-and to clamp blade 22 between them. Whenthe handle is rotated in the other direction, it allows guard 108 to descend until it strikes .bar 103. In this position the guard is free of pin 71 and may be rotated about pin 105. Guard 108 is pro vided with teeth 13 and 14, teeth 14 being longer than teeth 13 as in previous embodiments.

In Figs. 30 through 33 there is shown a one-piece razor in which the cap is pivotally secured to the guard. In this embodiment a handle 111 has threaded engagement with a bar or base member 112 and is rotatably journalled in a guard 113. Handle 111 is provided with internal threads 114 which are adapted to engage threads formed on pin 71 of cap 115. One end of cap 115 is provided with a bent pin 116, which extends in a direction parallel to the handle 111 and is rotatably and slidably journalled in an extension 117 of the guard. The lower end of pin 116 rests upon one end of bar 112. The bar is provided with projections 118 which extend into apertures'119 formed in guard 113. The guard is provided with teeth 13 and 14:, teeth 14: being longer than ,teetl1 13 as in previous embodiments.

When the handle is rotated so as to engage pin 71, it forces guard 113 against cap 115, the guard sliding upwardly on pin 116. When the handle is rotated in the opposite direction, pin 71 is first disengaged and further rotation of' the handle allows the guard to dro entirely clear of pin 71. The cap is held a ove the guard due to pin 116 bearing against bar 112. In this position the cap may be pivoted about pin 116 in order that the blade 22 may be removed.

In Figs. 34: through 38 there is shown a still further embodiment of a razor having the cap permanently secured to the handle and provided. with a guard capable of giving four difierent degrees of closeness of shave. This razor is adapted to be used with a blade having a central slot narrower than the opening ordinarily required for the passage of the central pin of the cap." The advantage of this is that a very narrow opening in the blade results in a blade in which the stresses produced due to flexing of the blade are uniformly distributed.

Reference character 120 designates a handle having an external thread 121. Thread 121 engages a similar thread formed in a bar or base member 122. A. cap 123 is hinged to bar 122 at 124. Bar 122 is provided with projections 125 which, when the cap is in closed position, extend through openings 126 formed in the cap. Cap 123 is provided with two thin members 127 extending fro-m its central portion. Members 127 have portions of a screw thread cut therein. The thread 121 of handle 120 is adapted to engage the portions of the thread formed on members 127.

A guard 128', which is shown as similar to the guard illustrated in Figs. 1 through 3, is positioned on bar 122 by means of projections 125. The ridges 17 on theguard are gggpted to extend into slots 129 formed in bar When handle 120 is rotated so as to advance upwardly, as shown inFig. 37, with respect to bar 122, the upper end of the ban-' dlc bears against the lower side of guard 128 and forces the guard up against cap 123. At the same time the threads 121 on the handle engage the portions of the thread cut in members 127 and thus securely holdithe cap in place. When the handle is rotated in the reason for this is so that members 127 will. be accurately positioned with respect to the threaded end of handle 120 so that the thread 121 on the handle will be assured of properly engaging the portions of the thread cut" on members 127.

In Fig. 38 there is shown, at one-half the scale used in the other figures, a blade adapted to be used in the modification last described. It will be noted that very little material has been removed from the center of the blade in order to provide the apertures. The centralaperture is too narrow to receive a full screw threaded round member adequate to clamp the blade. Instead of the three apertures extending crossways as shown, it is obvious that members 127 and projections 125 may be constructed so that their longer dimensions extend in a longitudinal direction.

Instead of having the member 127 as shown, a'pin attached to the cap may be used which has the sides filed off or otherwise formed to produce a narrow web with screw threads on the ends. In such case the handle would have an internally screw thread counter bore cooperating with the flattened pin.

It will thus be seen that I have provided a razor in which different degrees of closeness of shave may be obtained. I have fur ther provided a one-piece razor in which at least two different degrecs'of closeness are obtainable and a two-piece razor giving four different degrees. Further, in the two-piece razor the cap is permanently attached to the handle, while the guard is removable. Hence a user will seldom, if ever, drop the cap, which is apt to result in bending of the edges. The guard is so held on the razor that it is not apt to be dropped and the nature of a guard is such thatv drop ing it is not likely to injure it. Finally, I iave provided a razor in which may be used a blade having a narrower central slot than has heretofore been possible.

Although the novel features of pivoting or otherwise securing the parts together are shown in connection with the variable exposure, it will be readily apparent that the securing features may be used independently of the variable exposure feature. Also, any

of the forms of reversible guards illustrated in Figs. 1 through 15 may be employed in combination with any of the razors shown in Figs. 16 througln 38 which are adapted for a removable guard, and any of the means illustrated in the former figures for obtaining difi erent degrees of blade expo-sure without reversing the guard may be employed in the guards at any of the latter figures.
